MR-J3-11KA(4) to MR-J3-22KA(4)
Note 1. If operation that generates torque more than 100 of the rating is performed with an abnormally high frequency in a servo
motor stop status (servo lock status) or in a 30r/min or less low-speed operation status, the servo amplifier may fail even when
the electronic thermal relay protection is not activated.
2. The operation time at the load ratio of 300 to 350
applies when the maximum torque of HF-KP servo motor is increased to
350
.
3. The operation time at the load ratio of 300 to 400
applies when the maximum torque of HF-JP servo motor is increased to
400
.
